"The primary interest of this investigation is to understand the surface elastic wave properties in piezoelectric semiconductors and layered media. Generalized piezoelectric wave equations in piezoelectric semiconductors and layered media are derived. Systems considered are the piezoelectric semiconductor, the two layer piezoelectric insulator-semiconductor, the three layer piezoelectric insulator- gap-semiconductor and the four layer piezoelectric insulator-gap-semiconductor-dielectric substrate. The eigenwave expansion and the iteration methods in the complex domain are used to solve the problems. Mathematically, it represents a solution of the eigenvalue boundary value problem which involves iteration of functions in the complex domain. Solutions obtained are eigenvalues and eigenvectors which include all the information from the wave equations and the boundary conditions. The numerical calculations have been conducted for the above mentioned cases, with the conductivity, diffusitivity, carrier mobility, drift velocity, gap width, semiconductor layer width, permitivity of the dielectric substrat and frequency as the parameters. The gain in db per centimeter for various cases has been calculated for illustration and the results are found to be reasonable"--Abstract, page ii.
